Question

radical equation....square root -4+5u=-1

Answer 1

\[\sqrt{-4+5u}=-1\]

Answer 2

The square root of any nonnegative number is nonnegative. So the square root will NEVER be negative (unless you explicitly place a negative out front)

So the equation above is NEVER true for any value of 'u'

Answer 3

no solution then?

Answer 4

exactly, there are no solutions

Answer 5
